FOLDING CHAIR.

To all whom it may concern Be it known that LUDWIG SCHEIBE, cook,citizen of the German Republic, residing at Krolpa, Kr. Ziegenriick,Germany, have invented certain new and useful Improvements in orRelating to Folding Chairs, (for which I have filed applications inGermany,

Belgium, October 27, 1920; Denmark, O'ctober 28, .1920; Netherlands,October, 18, 1920; Swiss, October 28, 1920, and Great Britain, November16, 1920,) of which the following is a specification.

Various kinds of folding or collapsible chairs are known. One type ofcollapsible chair is folded by moving the lateral supporting memberstoward one another, the said members being operatively connected to eachother by scissor-like fittings or trellis-struts which are brought'fromthe closed to the open position when the chair is folded. The seat iscarried directly on supports secured to the upper ends of the trellisstruts and displaced when the chair is being folded. The flexible seatsags and forms a pocket when the chair is in the folded position so thatthe thickness of the material becomes clumsily packedbetween its twosupports and prevents the lateral members from being in contact. Thefolded chair therefore is not as compact as desired. The material 'ofthe seat is pinched and creased between the side members and is liableto get damaged when the chair is not opened for a long time. Anothersource of deterioration is that when the chair is in use the whole ofthe weight of the person seated thereon is borne by the flexible seatwhich is thus often torn. Finally when it is desired to fold the chairwith care, the forming of the pocket must be watched and assisted, thisrequiring attention. a This invention relates to a folding chair of thekind in which, as already referred to, the side members are moved towardeach other. The chair according to this invention is entirely free fromthe above-mentioned disadvantages in thatone side of the seat is securedto a rod arranged on one of the lateral members. The seat then passesover the side struts secured to the upper ends of the trellis struts orscissor members and its other end is secured to a spring-controlled rodmovably mounted on the opposite lateral member, and guided on thelatter. The seat is thus always stretched and Specification of LettersPatent.

slides under the action of the spring, over the side struts fastened tothe ends of the trellis struts when the chair is being folded orunfolded.

A construction of a folding arm-chair according to this invention isillustrated in b of the arm-chair comprise the arm rests n 0 and d andthe struts c f g h. The uprights of the frames at and b are providedwith slots 11 and 70 located above the struts g and h and adapted toreceive the pins Z and m of the upper ends of the scissor or trellisstruts o and p, the said ends being connected by rods 9 and 1' roundedoff toward the outside. The seat 8 passes over the said rods. In theconstruction illustrated in Fig. 1 one of the ends of the seat [ispermanently clamped between the side strut h and a similar rod 7", theother end being secured to a sliding rod t located above the side strutg and provided with a handle to to which one end of a spring 1) may befastened, the other end of said spring being secured to the lower strut6. Instead ofbeing fastened to the handle it the spring may pass througha suitable hole in the upper strut g and be directly attached to thesliding rod 25. The

baJck of the arm-chair comprises uprights w and y carried by the armrests c and d and supporting the back to.

Fig. 1 shows the arm-chair ready for use. The frames a and I) moveapart, the pins Z and m sliding in the slots 2' and 70 until the rods 9and 7' rest on the struts g and h, the sliding rod 25 being between thestrut g and the rod g. The seat s with its downturned sides gripped isready in this position to receive the occupant.

The arm-chair is folded by slightly raising the rods 9 and 1", afterwhich the lateral frames 0: and b are pushed toward one another (Fig. 3)so that the rod 1* slides under the seat 8 which at first lifts thesliding rod t The spring 0 becomes stretched untilit overcomesfrictional resistance and pulls the sliding rod t down into the positionillustrated in Fig. 4 so that the seat is never slack and does not sagin the folded position. If the spring 4: fails, the seat 8 may bestretched to its proper position by means of the handle u. The back tois folded in fanlike fashion.

bears against the rod g. I The chair accord- 'ing to this invention isvery light, is easily made and stored and is very stable even in itsmost simple construction.

I claim: I

1. A collapsible chair, the lateral members or frames of whichareconnected to one another by pivoted or trellis struts and in whichone side of the seat secured to one of the lateral frames passes overrods secured to the upper ends of the trellis struts, the other side ofthe said seat being secured to a spring-pulled sliding rod keeping theseat stretched in any position of the chair 2. A collapsible chair inaccordance with claim 1, wherein one side of the seat is pernection atthe upper ends thereof, cross rods between the upper ends of saidlazy-tongs, a flexible seat member fixedly secured at one end to one ofsaid frames and yieldingly secured at the other end to the other of saidframes, saidseat member passing over both of said cross rods, wherebythe seat member will always be kept taut whether the chair is in open orclosed position.

In testimony whereof I aflix my signature in presence of two witnesses,
